AIR Option 1: Technology Translation: Enabling High Efficiency & Clean Combustion through the Integration of Low Heat Rejection Concepts with Advanced Low Temperature Comb Eng

本次PFI：空气技术转化项目致力于转化低散热(LHR)和低温燃烧(LTC)的协同组合，以填补现有商用内燃机和清洁高效先进内燃机之间的技术差距。转换后的LHR/LTC技术具有以下独特的特点：低温内燃机的低放热，与传统或普通的低温内燃机相比，产生更有利的热力学。与领先的竞争内燃机相比，这提供了典范的效率、发动机排放的氮氧化物和固定碳，以及合适的排放温度，使排放控制系统能够良好地运行。该项目通过实施概念验证来实现其目标，该概念验证在压燃式发动机中通过LTC通过实验和计算实现了LHR概念，从而在轻型车用柴油发动机上实现了LHR/LTC燃烧模式的原型。这一合作伙伴关系与通用汽车公司接洽，通用汽车公司是轻型汽车发动机原型的工程师和制造商。通用汽车在全球汽车市场领域提供指导，如运营限制、成本限制和与适销对路的产品的技术集成，以便将LHR/LTC燃烧转化为可能导致竞争性商业现实的道路。预计未来10年潜在的经济影响将达到近4,000万美元(基于美国新登记的柴油车，平均每年可节省256美元的燃料成本，每加仑燃料成本为4.00美元)，这将有助于美国在汽车市场领域的竞争力。从长远来看，社会影响将是通过减少标准污染物(例如氮氧化物)的排放来改善车辆的燃油经济性，从而减少车辆的碳足迹。此外，这一努力将增加调查人员的人数？通过利用用于夏季STEM夏令营和课程重新设计活动的资源，努力增加STEM学科的女生和代表性不足的学生，并改善热力学方面的本科生课程教学。最后，将分发学术文章和会议演示文稿，以确保科学和技术途径的发现被公布。

This PFI: AIR Technology Translation project focuses on translating the synergistic combination of low heat rejection (LHR) and low temperature combustion (LTC) to fill the technological gap between existing commercially available internal combustion engines and the clean high-efficiency advanced combustion engine. The translated LHR/LTC technology has the following unique feature: low heat rejection from a low temperature combustion engine that results in more favorable thermodynamics compared to either conventional or ordinary low temperature combustion engines. This provides exemplary efficiency, engine-out exhaust emissions of nitrogen oxides and fixed carbon, and suitable exhaust temperatures for favorable operation of exhaust emission control systems when compared to the leading competing internal combustion engine. The project accomplishes its objectives by performing a proof-of-concept that experimentally and computationally realizes LHR concepts with LTC in a compression ignition engine resulting in a prototype LHR/LTC combustion mode operating in a light-duty automotive diesel engine. The partnership engages General Motors, which engineers and manufacturers the prototype-intended light-duty automotive engine. GM provides guidance in the global automotive market space such as operating constraints, cost limitations, and technology integration with a marketable product in order to translate LHR/LTC combustion along a path that may result in a competitive commercial reality. The potential economic impact is expected to be nearly $40million in the next 10 years (based on new diesel vehicle registrations in the United States demonstrating on average $256/year in fuel cost savings at $4.00/gallon fuel cost), which will contribute to the U.S. competitiveness in this automotive market space. The societal impact, long term, will be improved vehicle fuel economy with reduced emission of criteria pollutants (e.g., nitrogen oxides), thereby reducing vehicle carbon footprint. Additionally, this effort will augment the investigators? efforts to increase female and underrepresented students in STEM disciplines and improve undergraduate student course instruction in thermodynamics by leveraging resources used for summer STEM camps and course redesign activities. Finally, scholarly articles and conference presentations will be disseminated to ensure scientific and technological pathway discoveries are made known.
